g++ 5.1.0 not building project, clang shows unknown error

Question

I'm trying to build a simple project using biicode , including the catch cpp unit test library. For now I've a simple vanilla project with no extra declarations , looks something like

#define CATCH_CONFIG_MAIN 
#include "catch.hpp"
#include "cbs-algorithm-sort.hpp"

int returnInt(int n){ return n; };

TEST_CASE( "Sample test", "[Sample Test]" ) {
    REQUIRE( returnInt(1) == 1 );
    REQUIRE( returnInt(2) == 2 );
    REQUIRE( returnInt(3) == 6 );
    REQUIRE( returnInt(10) == 3628800 );
}

when building with g++ 5.1.0 , the following errors are shown and project never gets built:

I've no idea about errors generated by both compilers specially the clang one. Any kind of help would suffice.

Looks like `catch/include/catch_runner.hpp` has some diff output in it, maybe a partial version control merge or something. I'd make sure that your local copy of the library code is clean and up to date. — TartanLlama, Jun 09 '15 at 11:20
What's there on the line 63 of `catch_runner.hpp`? Looks like merge conflict. — Anton Savin, Jun 09 '15 at 11:20

Usually, the single header version of catch has less problems, you can try my own copy in https://www.biicode.com/diego/catch — drodri, Jun 09 '15 at 17:34

You most likely have a git merge, either in progress or aborted. These:

<<<<<<< HEAD

=================

>>>>>>> 7f5615272b0fb51bcd7a669e68f3b4c7a87d93bb

are the markers git places where version conflicts arise that cannot be solved automatically. Search for all occurences of <<<<<, do the required edits, possibly commit and then recompile.

If it isn't your code, maybe downloading or cloning again will be a quick solution.

yes this is it. However biicode won't let me modify code since on each find it is going to download this very file. I've filed an issue on github repo. Thanks :) – Abhinav Gauniyal Jun 09 '15 at 11:31
I would like to add , this does solves the problem by making it possible to build with clang++ however g++ fails to build with same errors. – Abhinav Gauniyal Jun 09 '15 at 11:40
You can override the dependency like this: http://docs.biicode.com/c++/advanced/override_deps.html – amalulla Jun 09 '15 at 17:48

g++ 5.1.0 not building project, clang shows unknown error
